Definitions
- the present invention relates to copolymers comprising at least structural motives of two polyethers of different chain length as well as carboxylates.
- the present invention also relates to the use of such copolymers as plasticizers for mineral binder compositions.
- copolymers of the present invention have been found to yield a high initial slump flow of mineral binder compositions and to retain a high slump flow thereof over longer periods of time.
- Copolymers of polycarboxylic acid and alkoxylated, ethylenically unsaturated alcohols are known for many years as dispersion aids for aqueous dispersions, especially for aqueous dispersions of mineral binders. Such copolymers are frequently being called polycarboxylate ethers (PCE).
- PCE act as superplasticizers and reduce the water needed to achieve a certain level of fluidity of a given uncured mineral binder composition. A reduction of water in mineral binder compositions, especially in cementitious compositions, is desirable as it leads to less segregation of solid components in the uncured composition and to an increased compressive strength of the cured composition.
- WO 2016/074984 (BASF SE ) teaches PCE which are copolymers having polyether side chains of different length where one side chain is short (5 - 35 alkylene oxide repeating units) and the other side chain significantly longer (45 - 150 alkylene oxide repeating units).
- WO2016/074984 is concerned with copolymers derived from alkoxylated hydroxybutylvinyl ether monomers.
- PCE which are copolymers comprising two different alkenyl polyethers and their production, the copolymers being derived from mixtures of ethoxylated methallyl alcohol and ethoxylated isoprenyl alcohol. Additionally, the number of repeating units of the copolymer's side chains is 32 - 44 where units derived from ethoxylated methallyl alcohol are present and is 52 - 62 where units derived from ethoxylated isoprenyl alcohol are present.
- PCE-type copolymers described in the prior art are not in all cases the best choice as plasticizers for mineral binder composition.
- mineral binder compositions have a large variation in possible components. Different mineral binders used, different aggregates used, different mix ratios of components, etc. may require different copolymers as plasticizers. This is especially the case with the more widespread use of manufactured sand and high alkali concrete.
- Another reason is that many PCE-type copolymers lead to a reduction in the development of compressive strength and even to a lower final compressive strength of cured mineral binder compositions. Lower compressive strength is normally not desired. There is thus a constant need for improved PCE-type copolymers to influence the water demand and/or the rheology of mineral binder compositions.
- PCE-type copolymers suitable as superplasticizers for mineral binder compositions, especially for cementitious binder compositions.
- the PCE-type copolymers are suitable as superplasticizers for mineral binder compositions, especially for cementitious binder compositions.
- copolymers as claimed in claim 1 can solve one or more of these objectives.
- copolymers derived from a combination of alkoxylated, ethylenically unsaturated alcohols with medium chain length (20 - 60 alkylene oxide repeating units) and of alkoxylated, ethylenically unsaturated alcohols with long chain length (65 - 150 alkylene oxide repeating units) leads to high initial slump flow, good retention of slump flow over time, and increased compressive strength.
- the ethylenically unsaturated alcohol with medium degree of alkoxylation (20 - 60 repeating units) is selected from vinyl alcohol, vinyl-4-hydroxybutyl alcohol, (meth)allyl alcohol, or isoprenyl alcohol and where the ethylenically unsaturated alcohol with high degree of alkoxylation (65 - 150 repeating units) is selected from vinyl alcohol or vinyl-4-hydroxybutyl alcohol.
